You must edit the runtime-config.properties files for the VMware Identity Manager appliances in the secondary data center to change the JDBC URL to point to the database in the secondary data center and to configure the appliance for read-only access.

1

Using a ssh client, log in to the VMware Identity Manager appliance as the root user.

2

Open the runtime-config.properties file at /usr/local/horizon/conf/runtime-config.properties.

3

Change the JDBC URL to point to the database for the secondary data center.

See Add an External Database to the VMware Identity Manager Appliance.

4

Configure the VMware Identity Manager appliance to have read-only access.

Type read.only.service=true.

5

Restart the Tomcat server on the appliance.

service horizon-workspace restart

Repeat these steps on each VMware Identity Manager appliance in the secondary data center.
